TinyMCEPlugin

This is an integration of the WYSIWYG editor. This is great little editor, fast and highly functional, and supporting a wide range of browsers, including Firefox, IE and Safari. At the time of writing it doesn't work with Opera or Konqueror.

Unlike the other editor integrations in TWiki, which install "Word in a Browser" style editors, this plugin is able to swap out the standard text areas in an edit and replace them with WYSIWYG editors. This means you get WYSIWYG editors for textareas in forms, as well as for the main text of the topic. It can also co-exist alongside other WYSIWYG editors, such as Kupu.

The editor automatically "switches itself off" (i.e. reverts to the old text-only window) when editing topics that contain TWiki content it can't handle, such as complex TWiki variables.

Editor Notes

The editor uses a translator module to convert from TWiki markup language (TML) to HTML and back. The translator converts special TWiki tags - such as %VARIABLES% - to plain text, and encloses them within HTML spans using a special style called WYSIWYG_PROTECTED. In this way the editor can detect text that is not meant to be HTML formatted. This style is also used to protect special text you enter into the editor from being interpreted when the topic is translated back into TML. If you want to add any special TWiki features that are sensitive to formatting, such as Set statements, then you have to format those regions using 'Protect on save' or 'Protect forever'.

Installation Instructions

NOTES:

This plugin comes pre-installed on TWiki 4.2.X. You should only need to re-install if there is an upgrade to the plugin.

It requires the very latest revision of WysiwygPlugin. It will not work with the version shipped with TWiki 4.1.2.

When installed, it replaces the old "textarea" editor. If you want to maintain access to the old editor from the standard screens, follow the instructions under Configuring the buttons on TWiki < 4.2.0.

First follow the installation instructions to install the Plugin:

You do not need to install anything in the browser to use this extension. The following instructions are for the administrator who installs the extension on the server where TWiki is running.

Like many other TWiki extensions, this module is shipped with a fully
automatic installer script written using the BuildContrib.

If you have TWiki 4.2 or later, you can install from the configure interface (Go to Plugins->Find More Extensions)

Settings

You can override this setting by defining TINYMCEPLUGIN_DEBUG to enable some simple debug features.

Set DEBUG = 0

This setting contains all the options passed to the TinyMCE editor on startup.
For a full explanation of the available options, and guidance on reconfiguring TinyMCE , see the Moxicode TinyMCE Wiki. Note the inclusion of the Pattern Skin standard CSS files in the content_css setting.

Warning: if you enable paste_auto_cleanup_on_paste then it automatically implies =past_use_dialog on all non-MSIE browsers.

Set INIT_MSIE = paste_auto_cleanup_on_paste : true

Set INIT_OPERA =

Set INIT_GECKO =

Set INIT_SAFARI =

You can override these settings in the same way as any other TWiki variable, by setting e.g. TINYMCEPLUGIN_INIT in the site, web or topic preferences. You are not recommended to edit the setting here.

You can disable the plugin in any web or topic, or for any specific user, by setting the TINYMCEPLUGIN_DISABLE variable to 1.

Some browsers don't support TinyMCE. You can prevent the editor from being invoked on these browsers by setting TINYMCEPLUGIN_BAD_BROWSERS to a regular expression that matches the user-agent string for any broken browsers. The default is (?i-xsm:Konqueror|Opera).

The global TWiki Variable WYSIWYG_EXCLUDE can be set to make the plugin sensitive to what is in a topic, before allowing it to be edited. You can set it up to veto an edit if the topic contains:

html - HTML tags (e.g. <div>, not including <br>), or

variables - simple variables (e.g. %VAR%) or

calls - TWiki variables with parameters e.g. %VARIABLE{...}%

pre blocks (<pre>)

HTML comments (<!-- ... -->)

If the plugin detects an excluded construct in the topic, it will refuse to allow the edit and will redirect to the default editor.

If you excluded calls in WYSIWYG_EXCLUDE, you can still define a subset of TWiki variables that do not block edits. this is done in the global TWiki variable WYSIWYG_EDITABLE_CALLS, which should be a list of TWiki variable names separated by vertical bars, with no spaces, e.g: * Set WYSIWYG_EDITABLE_CALLS = COMMENT|CALENDAR|INCLUDE

You can define the global variable WYSIWYGPLUGIN_STICKYBITS to stop the
plugin from ever trying to convert specific HTML tags into
HTML when certain specific attributes are present on the tag. This is most
useful when you have styling or alignment information in tags that must be
preserved.

This variable is used to tell the translator which attributes, when present
on a tag, make it "stick" i.e. block conversion. For example, setting it to
table=background,lang;tr=valign will stop the translator from trying to
handle any table tag that has background or lang attributes, and any
tr tag that has a valign attribute.

You can use perl regular expressions to match tag and attribute names, so .*=id,on.* will ensure that any tag with an on* event handler is kept as HTML.

If you edit using the plain-text editor, you can use the <sticky>..</sticky> tags to delimit HTML (or TML) that you do not want to be WYSIWYG edited.

Configuring the buttons on TWiki < 4.2.0

When installed on TWiki versions before 4.2.0, this plugin replaces the old textarea editor with the TinyMCE editor. The shock of this change can be too much for some older contributors, so we have written instructions for reconfiguring your templates in TWiki:Plugins.TinyMCEFrequentlyAskedQuestions.

TWikibug:Item4946: I think I have finally fixed non-iso-8859-1 character sets. Painful.

31 Mar 2008

TWikibug:Item5314: TWikibug:Item5457: Fixed pickaxe mode for editing UTF-8. Characters above 255 are converted to entitites, which is a bit of a PITA, but at least it no longer corrupts topics. NOTE: YOU MUST UPGRADE WysiwygPlugin TO 16600 OR LATER

TWikibug:Item5047: disable save and preview during page load TWikibug:Item5111: make the entry in the format menu sensitive to where the cursor is TWikibug:Item5022: made TT font size same as verbatim. Had to add a new style to do it, as TMCE didn't want to play with TT or CODE tags.

TWikibug:Item4630: polished up the way the secret string is done, to ensure synch between perl and JS. TWikibug:Item4622: added UTF-8 handling steps that fixup malformed UTF8 strings before presenting them to the editor (saves Moz) and stops the editor passing them back to TWiki (saves IE). TWikibug:Item4603: added the draft help, so we can at least build the beta without the nasty warning
